Bahri Batuhan Bilecen

PhD student at ETH Zürich

Hi there 👋 I'm a PhD student at ETH Zürich and Max Planck Institute, under the supervision of Prof. Siyu Tang, Prof. Bernt Schiele, and Dr. Jan Eric Lenssen, with CLS fellowship.

I focus on generative modeling, representation learning, and video-language-action models.

I got my CS MSc at Bilkent University in 2025, and EEE BSc at Middle East Technical University (METU) in 2022. I also worked as a full-time research engineer at Aselsan Inc. in 2021-2025. My MSc thesis focused on 3D reconstruction from single images with generative models, under the supervision of Prof. Aysegul Dundar.
